ACT T1RR-H04 Twin Disc Sintered Iron Race Clutch Kit for Honda Civic and Acura RSX

The ACT T1RR-H04 Twin Disc Sintered Iron Race Kit is engineered for high-performance racing enthusiasts seeking a direct bolt-in solution that requires no additional modifications. This kit features ACT's sintered iron race discs, which deliver the highest torque capacity among ACT's race disc offerings and boast ultra-high heat resistance, ensuring durability under severe racing conditions. Designed with a rigid, heat-treated chromoly hub, the kit provides long-lasting strength and precise engagement, making it ideal for high horsepower applications. The included CNC-machined and dynamically balanced flywheel guarantees smooth operation and reliability at high RPMs, while the four-stage heat treatment process on all diaphragms enhances longevity. All components are meticulously assembled and tested for quality assurance, including a 100% clamp load test for consistent performance. The kit's design increases pedal load by approximately 10-20% over stock, with an 80-90% increase in clamp load, resulting in predictable, quick engagement, increased throttle response, and a slight increase in gear rattle, suited for racing environments. This kit includes a pressure plate, two high-performance discs, a floater, flywheel, and an alignment tool, with some packages also containing a pilot and release bearing. It meets SFI Specification 1.2 standards, confirming its suitability for competitive race use. The ACT Twin Disc Race Kit is recommended exclusively for high horsepower racing applications and is not intended for street use. Backed by ACT's industry-leading one-year warranty, this kit provides dependable performance and long-term durability for serious racers looking to maximize their vehicle's clutch capabilities.
